STEP 1: Preheat the oven to 400 degrees F. Pat the haddock fillets dry with a paper towel and grease the bottom of a 9×13 inch baking dish with olive oil or cooking spray.
STEP 2: Season the haddock all over with salt and pepper.
STEP 3: In a food processor add the crackers and process to form a fine crumb, but do not overprocess. Mix in the garlic powder and optional any additional seasonings.
STEP 4: Prepare a breading station with three plates with a rim. Put the flour into the first plate. In the second plate add whisked eggs. Transfer the crackers crumble into the third plate.
STEP 5: Dip and thoroughly coat each fish fillet in the flour, then the egg, and finally the cracker crumbs. Set the breaded fish on the prepared baking dish in a single layer.
STEP 6: Bake for 10-12 minutes, until the fish is cooked through, and the internal temperature reaches 145 degrees F. Serve immediately.
